Into the Limelight: The Women Who've Made Sexual Accusations Against Cain -- PICTURES

In a television interview on Monday, an Atlanta businesswoman alleged she had a 13-year affair with Republican presidential candidate Herman Cain. In a pre-emptive statement on CNN, Cain said he did not have an affair and described the fourth accuser, Ginger White, as a "friend" but said there was nothing sexual between them.

A third woman who worked for the National Restaurant Association, and who remains anonymous, also claimed Cain sexually harassed her.

She is one of two women who settled with the National Restaurant Association after lodging sexual harassment charges against Herman Cain. Until Tuesday, her lawyer, Joelt, spoke on her behalf.(AP Photo/APTN)
